Test ID:1.3.6.1.4.1.25623.1.1.2.2020.2374
Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for ntp (EulerOS-SA-2020-2374)
Summary:The remote host is missing an update for the Huawei EulerOS; 'ntp' package(s) announced via the EulerOS-SA-2020-2374 advisory.
Description:Summary:
The remote host is missing an update for the Huawei EulerOS
'ntp' package(s) announced via the EulerOS-SA-2020-2374 advisory.

Vulnerability Insight:
Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array.(CVE-2018-7183)

ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the 'received' timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704.(CVE-2018-7184)

The broadcast mode replay prevention functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to cause a denial of service (reject broadcast mode packets) via a crafted broadcast mode packet.(CVE-2016-7427)

ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance.(CVE-2020-13817)

Affected Software/OS:
'ntp' package(s) on Huawei EulerOS V2.0SP2.

Solution:
Please install the updated package(s).
